Preparation

• In an 8-quart pot, heat the olive oil over medium heat. Add the leek and 1/2 tsp. of the pepper, and cook, stirring often, until the leek is tender and beginning to brown, 3 to 5 minutes. Add the broccoli rabe, toss, and cook until the leaves have wilted, about 1 minute. Reduce the heat to low, and add the garlic and the remaining pepper. Cover and cook, stirring occasionally, until the stalks are tender, 12 to 13 minutes. Stir in the butter until melted, season to taste with salt, and serve.
